Richard Linklater, whose film Boyhood is currently in theaters, has reportedly departed the planned Warner Bros. remake of The Incredible Mr. Limpet.

Sources who spoke with exclusively with The Hollywood Reporter, dropped the news Linklater is expected to exit a project he has been attached to for three years due to his busy schedule.

Linklater has decided that he wants to focus on his passion project, the 1980s-set That's What I'm Talking About. The film is based upon the director's life and would follow several students in their first year at college. It is said to be similar to Linklater's popular film Dazed & Confused, which was set in the 1970s.

The sources say that he is aiming to try an begin filming Talking About in the fall and it is believed that he could also be busy during awards season due to promoting Boyhood. On top of that, Linklater is also attached to direct an adaptation of Daniel Asa Rose's memorial Larry Kidney, which has Zach Galifianakis and Will Ferrell starring.

With no director, it leaves Warner Bros. remake of the 1964 film The Incredible Mr. Limpet in flux. The film seemed to be nearly finished with casting in early July when Galifianakis and several others joined the project.

Galifianakis would play Larry Limpet in the film, which follows a man who finds himself turned into a fish. Hamm was set to play an evil human businessmen, with Silverman and McBride playing other human characters, while the rest would be voice actors.
